Beit kn'otm th'at'I, GILE J. WILLs0N,of Bending, Berks egounty, and State of Pennsylvania',`have invented anew and useful Improvement in Wateh-Cases and I do hereby declare that the following is a full, clear,

-zmd'exuet description thereof, which will ennble others skilled in tbe art'to make and usc'thefsame', reference being had to theacco'niponying drawings forming part of thisispeciiication;

The present inve'ntion mainly relates tonny kind of a watch-case, the movement of ivhielr has not a mova-l blc cap to protect it from dustnnd broken euse-springs entering the njorning parts of vthe watch. l A

vThe objectof'this invention is to"protect'such untclifxnoverncnts from being stopped by the above muses,-

it consisting in providinga seperate entire ring, to be applied to theinner part of the centro of a watclncase of any convenient metal or'material, the one edge forming-a shoulder or bearing-to receive the watchmovcmont,

` and the other or lou'ct edgetend'itsbeariug on t'ne lower flange ofthe centre of the watch-caso, thereby fox-in'- ment of thc'n'atch, thclmoveme'nt o f the-u ateh'heingl fastened into the case in the usual manner.,

ing an insdelining to the centreof the watch-case, thereby excluding the possibiiity--of dust working into the movement through or around the pnsher tothe cup-spring of a hunting-case watch, into the movement of the watch; also said ring or lining prevents tho.'po'ssibility of broken cop lor ense-springs from entering the xnove- It'j also consists in a. key-hole protector in the form of u tube, which may pass from the cap of the watch. 0WD i0 the Uitpcf "pinto o fJ-b. llillelmint.,eitherv4 inside or ontsidczi' theilnnge, usnellyaronnd the winding.-

stem of thofyrsteh, and finding its bearingl onsaidpla'.-e,`ou some clastiematerial to for-mnu'air-tightjoinn When saidtub'e is passed inside of the flange to the'ninding-stem, and the lower end clo'scrl, so` as only to admit of the stern turning freely in winding, it will act, in opening t'ne cap to which it is attached, asaeleanerof the recess, or ang' ni'o'nndV the Winding-stem, throwing out any deposits from the winding'ikcy of the watch and radmitting the vinding-irey to'pass on to the' stem without any obstruction, and preventing either dust or dirt io'f any kind from psssingthrongh the key-holeinto the movement of the watch. I

-In nccompnnyingplste of drawings, my improvements in-uatch-cnses nre illustrated.

H H shoiv the winding-stem and ,the key-hole protector in the two forms described, one iviththo :protector or tube, passing ldowninside, and the other outside of the ange around the stern; I, the red shading', shows the packing attire bottom of tube or key-hole protector, which-said tube or protector finds` its bear-- ing upon, thus forming an a'r-tightjoint, to prevlcntvdirtor any other deposits from passing into the works of theowatch. J is the usual cup or ange surrounding the winding-stoms of watches.A K is the tube or protector,

extending `from cap of watch down around-,nindingLstem to the movement of the watch, to prevent dust orA dirt;

entering, s above described. Section E F represents-cap and the upper plato'of movement, {double'size show-v ing the dust-protector to key-hole, and its connection with cap, and its-bearing on the top of movement inside and outside of cup nround the winding-stem,' and the packing-upon which said tube forms ajoint or bearing air-tight.

' I am :more that rings encircling the movements in various kinds of'tvatches have been nsed for the purpose of protecting the movements from dust, but such rings have rested upon the movement-plate, and Have formed .n port thereof. I um also aware that encircling rings have'been used in the cases-.of watches, bu'tsucb. rings have been elastic, and have not been made entire, beingsprung into the case, but such is vnot; the character of niy invention. i d I.

Having thus fully described 'my invention, what I-desire to claim und secure as my invention by 4Letters Patent, are as follows: i

1. 'The application of nseparato entire ring to the centre of an ordinary mitch-oase, (new-or (116,) which 'the movement ofthe nre-tch will connect with, n the manner set forth, made of any convenient material, and of :my s'ze, shape, or form, to answer the pnl-poses set forth. v

2.' The applcaton of a. concal-ponted tube, with its bearing or packng on the movement of a watch or- 4some elstc substance, and connected 'with the cap ofthe watch in any convenient manner, to answer the purposes set forth.
